The victory will likely vault the second-seeded Guzick past Wong in the USTA national rankings. Guzick came into the tournament ranked No. 4 nationally while Wong was third.

It is Guzick's second title this month. She stepped up to the 16s and won the National Open in Montgomery, Ala.

"I've always wanted to win one my first year [in an age division] because I always want to do better in the higher age group," said Guzick, who will be an eighth-grader this fall at Christ Church Episcopal School in Greenville, S.C. "I've already done better than I did last year in 12s and I'm in 14s, so I'm happy."

Wong advanced to the Sweet 16 last year before falling to the No. 1 seed. This year, the Jackson, Miss., standout breezed through her first six matches en route to the final, dropping only two sets along the way.

However, Wong didn't have many answers for the left-handed Guzick. She struggled from the start.

"I wasn't really playing my best, and Sarah played pretty good," Wong said. "I just never got in a groove from the beginning. She was keeping me way behind the baseline."

Guzick jumped in front 5-1 in the first set and was never headed. Wong won the first game of the second set, but Guzick quickly rattled off four straight games to regain the momentum and a 4-1 lead.

"I just felt like being consistent [was the key], keep hitting hard and deep so she couldn't hit it with that much slice," Guzick said. "She did well with her slice, she just didn't play very well. That was too bad, but it's nice for me."

Marco Island's Lauren Embree defeated Asia Muhammad of Henderson, Nev., 7-6 (4), 6-2 for third place. Embree also won the tournament's sportsmanship award. Muhammad and Krista Damico, of Parker, Colo., won the doubles.

Dora Castorri, who has worked with the tournament since 1986, was honored for her service and given a key to the city of Plantation.
